无线局域网中的安全及WPA加密技术研究

Study of Security and Encrypt Technology on WLAN

安全对于无线局域网（WLAN）领域，是一个严峻的话题。本文从无线局域网的安全现状、安全问题入手，列举了黑客攻击的常用手段，介绍了现有的无线网络安全机制。在此基础上引出了在无线网中可用的多种安全加密技术，其中详细分析了Wi-Fi保护访问（WPA）。

In Wireless Local Area Network（WLAN） domain, securely is a stern topic, the regarding and the argument also never stopped. The paper starts from the security present situation and the security problem,lists the hacker attack method that they use commonly, introduces existing safety mechanism, in this foundation, draws out many kinds of securities encryption technology which in the WLAN might use, analysises the Wi-Fi Protected Access exhaustively.
